Looking forward: It won’t make the average hard drive faster. But adding support for them to the NVMe specification paves the way for faster ones coming to the pipeline and for overall storage to finally migrate from SATA after two decades.
Version 2.0 of the NVMe (non-volatile memory express) standard comes with new functionality and improved performance as expected. but also supports smaller hard drives
The SATA III interface used by all HDDs and many SSDs is showing its age every day. The last major update was in 2008, peak throughput of 600 MB/s has become a performance bottleneck for SSDs as the NVMe specification allows them to reach full speed through the PCIe band interface. high wid
NVMe is now adding support for Today̵7;s HDDs are still limited by the operating speeds of the read and write arms within the drive itself. For the most part, it’s far from saturating the SATA III interface like SSDs can. Once again, Seagate’s new Mach.2 comes close with sequential data transfers of up to 524 MB/s. Impressive for what is called “Rust rust” and even stepping on a budget SATA SSD.
As HDD size continues to increase to meet server and data center demands. Dual actuator drives such as Mach.2 may grow more common. but for consumers The most tangible benefit is the simplification of storage devices as a single solution between version 2.0 that added support for hard drives. and the overhaul is a modular requirement. The clear intention is for NVMe to become a universal interface for storage drives. Interface integration and potentially freeing up more space on crowded consumer motherboards.
Again, with the NVMe standard being prepared for “Life After SATA,” it may take some time until HDDs with interfaces start shipping and selling in large quantities. And it’s still going to be much longer until they start replacing dual SATA in the consumer space.
The NVMe 2.0 revision also introduces a number of SSD-specific features aimed primarily at improving control, durability, and cost. And of particular note is the introduction of Zoned Namespaces (ZNS), which help both drives and hosts decide on the physical location of Drive data to help increase capacity and performance. and as expected It will still be compatible with earlier versions of the specification.
